Phelps遇到了前所未有的危险，他的团队试图拯救他，同时还要阻止恐怖组织的阴谋，一个小镇到底有多少人在这阴谋里，究竟是怎么一回事

Jim Phelps es secuestrado por los habitantes de un pueblo tras enterarse que son parte de una red de criminales. El reloj corre mientras un par de asesinos están en camino para cometer un asesinato. La "Fuerza" debe encontrar y salvar a Jim, y luego tratar de detener el inminente asesinato.

Alors que Jim apprend par hasard l'existence d'un complot soviétique, on lui administre du poison pour tenter de le neutraliser. Les autres membres de l'équipe vont devoir non seulement sauver leur chef, mais aussi contrecarrer les plans des espions qui voulaient sa mort.

On holiday and going to meet Rollin at a mountain lodge, Jim stops off in a small town. However, a young couple drop a package containing a gas gun. Exposed, an old man named Doc takes Jim prisoner. The town is populated entirely by enemy agents and they plan to kill a Societ defector in L.A. Doc shoots Jim with curare and the young couple head off to kill the defector. When Rollin arrives, Doc claims Jim had a stroke and can't be moved, but Jim clues him in by blinking a warning in Morse code. Rollin mobilizes the team. Cinnamon goes in as Mrs. Jim and Barney as her chauffeur, and Willy as a trucker. Together the four of them have to get Jim out and thwart the assassination plot.
